What is a Watershed?

A watershed is defined as an area of land that drains to a common point. That common point may be a lake, an outlet to a river, or any point within a river system. The Big Walnut and Deer Creek Watershed is approximately 271,000 acres and lies mostly within three counties – Boone, Hendricks, and Putnam. The watershed is dominated by agricultural landuse with the exception of a few towns and the City of Greencastle.

New Public Presentation Ready for Viewing

The Big Walnut Watershed Alliance has recently created a PowerPoint presentation about our area’s water resources, their quality, and how all landowners can make a difference. Watershed alliance members are happy to give the presentation, for free, at homeowner association meetings, community/civic organization meetings, and nearly any other gathering where our message can be utilized. Please contact us if you would like to set up a time to hear this new information!
